I laughed when I played the Genesis version the first time after getting good at the SMS version and beating that. Something happened and when the final boss appeared he got killed instantly by falling in the pit or something strange. I was like "well that was an easy win!"
one of my favorite series. i own the cabinet. for all the sequels though, i think the NES (and later SNES) versions are the definitive sequels. especially the NES DD2. what a masterpiece.
